Hi all, This is from the Audio_Unit_Effect_with_Cocoa_View, the basic AU that changes the gain. I modified it so that one channel has increasing gain from 0.0 -> 1.0 and the other channel has decreasing gain from 0.0->1.0. My plan was to do output = input * (1-gain) for even samples, and output = input * gain for odd ones.

The result is that the slider has no effect on gain at all. What wrong assumptions am I making?

Your assuming the samples are interleaved -- they aren't. Each buffer that MyVolumeUnit::MyVolumeUnitKernel::Process() sees is a discrete channel of audio. You are seeing a effect, but it is likely not what you are expecting at all (and would be somewhat difficult to detect regardless).

Failure is not an option. It is a privilege reserved for those who try.
